Installation of Tekonsha Brake Controller Adapter
This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.
To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.
This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

2010 Dodge Ram Pickup
Purchased the Tekonsa Primus IQ controller with wiring adapter for my Dodge Ram. Shipment arrived quickly and was exactly what I needed. Installation was a piece of cake. Cut an opening in the plastic stock dash location. Plugged the adapter into the Dodge plug under the dash and into the Primus. Worked perfectly. No fuss. Installed in about 10 minutes which included the time to cut the opening.. Picture will be poster...
I was so happy with the service from etrailers that I ordered the Blue Ox Swaypro hitch. Thanks ETrailer.com!
by: Josh B.03/30/2024
I'm sure the product is great, but it does not work with my truck at all. Everything connects, all fuses are good but it receives no power. I had better luck with a cheap one from Amazon prior to this expensive one.
by: Cheapskate07/16/2020
Bought a Tekonsha P3 Trailer brake controller for my RAM 3500 HD when the OEM unit failed. A bit of work is needed to mount it but was well worth the price and effort to install. Simple to set up and adjust as the new brakes wore in. Braking with my 9750 pounds 5th wheel is now superb. The picture shows the final assembly just before popping the unit into the spot where the original unit was installed. My advice is: forget the factory unit, just buy one of these and enjoy your towing experience.
by: Ken L03/05/2015
Everything arrived on time and as advertised. Installation went without a hitch. The imbedded controller was removed without a problem and the wiring adapter worked as advertised. The EVIC does display an error but is easily corrected by depressing the back button before shifting into gear, Another good experience with etrailer!

Very easy conversion from factory unit. Slightly trimmed the factory dash where the OEM unit was located. New conversion plug was a perfect match. I highly recommend this unit over the expensive factory replacement

Bought this to temporarily install my prodigy controller until I got a factory controller for my ram. This harness was so easy to install (2 minutes) and works so good I think I am going to just keep this setup and save the $200 for controller and $50 to get the EVIC programmed. For $15 you can't go wrong!
by: Mitchell08/31/2021
it works as it should but now i am getting a light on my truck that says service trailer brake system. i hate check engine lights. i didnt know by not using the factory electric brake system it would throw a code but the main thing is that my trailer brakes work. it was very easy to install and so far so good

You will probably have to visit a Ram dealer to have them reconfigure the TIPM system so that you can get rid of the code. Check out the FAQ article that I have attached about using an aftermarket brake controller on a 2010 and up Ram trucks with integrated controllers:

Great product, plugged right in and made the installation a piece of cake!
The controller I bought was the P2, after a bit of cutting it went right in the hole where I believe the optional factory controller would have been.
I did cut a bit further down than I should have.

I bought this controller with the adapter harness to fit my 2012 Ram. I installed it in the location the factory controller would go into in about 15 minutes. Plugged right in and worked great. I couldn't be happier with it.

Don’t pay for two day shipping. The product and service were great the shipping was not timely.
by: Roger03/08/2022
Your website sold me on whether to purchase from etrailer. Other sites did not show or describe the products to assure me that the product would fit my needs and my vehicle. Even my local trailer supply store was no help and cost was more.

Controller did not seem to be working at first but after some use, it was fine. I had new brakes and drums and I think they just had to self adjust with use use.

Quick shipment worked great saved a lot of time instead of splicing wires under a dashboard just plug in both ends & your done. when you are changing your brake controller from a Ford f 150 to a Dodge Ram its the way to go.

Good no problems works great
by: Dutch J.12/08/2014
Hey it's just a wiring connector, but it has to be the right one for your vehicle and device. Mine was and saved a lot of work under the dash for just a little money. Take a close look or photo of your socket and make sure you are ordering the correct configuration. They may change designs from one year to the next. Zoom in on the product description pictures and insure it is a match for your truck.

2012 Dodge Ram Pickup
Purchased this product, along with the Tekonsha Prodigy P3 brake controller, to replace an OEM brake controller in my 2012 Ram 3500 which was a timed unit, as contrasted with the P3's proportional braking action. This adapter fit the OEM plug perfectly, and braking function is now, at least in my opinion, greatly improved on all my trailers. Thanks, Tekonsha and eTrailer!
(There was a minor aggravation which had nothing to do with the eTrailer parts; with the OEM unit unplugged and out of the system, the onboard computer turned on a red light on the dash, and an occasional message to "service the trailer brake system". Dealer techs tell me they can't turn it off, and I've gotten used to it. Just a FYI for any one who embarks on the same path as I did - it will either save you time at the dealer, or expose you to more knowledgeable dealer techs than I had....) JM

Very fast shipping. Brake controller was very easy to install with the factory harness adaptor. Seems to work great, very happy.

Works great still. Just be aware that steep driveways throw off the sensor and sometimes lock up the trailer brakes. Very easy and reliable on the road.

2015 Dodge Ram Pickup
This quality cable is exactly what is required to connect a non factory electronic brake control to a 2015 Ram 1500 factory trailer brake wiring harness. (Note - you can unplug the factory RAM Trailer brake control and the truck will not complain. I had to use specialized brake control for a towed vehicle brake system which is why the Ram factory control had to be disconnected.)
by: Michael08/17/2023
Good information and super fast delivery. Thank you
by: Ed04/11/2014
I bought the brake controller from them for an earlier truck. I recently bought a newer truck and ask which connector I needed to re-use my brake controller(which by the way works fantastic). I got a very quick response for the correct connector. Took a whole 2 mins to re-install the controller and wire and works great. Thanks again for your great service. Would highly recommend eTrailer and the Tekonsha brake controller.
by: Micheal M08/07/2013
Love this! So awesome, all I had to do was plug it in on both ends and PRESTO - trailer brakes. So easy... And since you created the special where the wiring harness and the P-3 Controller was a package, I actually PAID LESS than what your competitors were charging for just the P-3controller. Great job!

- Green Light on Tekonsha Voyager # 39510 is Constantly OnIf the Green light is constantly on when you trailer is disconnected then you have a short on the Blue wire somewhere or it has been wired incorrectly. The Blue wire on the Tekonsha Voyager # 39510 is the wire that carries the signal from your brake controller to the 7-Way on your 2012 Dodge Ram 1500 to activate your trailer brakes. If you are using the Adapter # 3021-P to connect it to your Ram then the wiring is most likely shorted somewhere. Check the pin in the 5 O'clock position (see...

- Will a Tekonsha Brake Controller Harness from a 2010 Ram 1500 Fit a 2013 Ram 1500I have an adapter that will work with a 2013 Ram 1500, but unfortunately Ram switched things up between 2010 and 2013 and the brake controller harnesses are different. Part # 3021-P fits the 2010 models and 2013 requires # 3023-P. I've attached an installation video on a 2013 model for you to check out to see the differences.
view full answer... - Recommended Replacement Brake Controller for a Factory Brake Controller in a 2012 Ram 1500You can definitely install an aftermarket brake controller on your 2012 Ram 1500, and the Tekonsha P2 # 90885 is a fantastic option. Working with trailer that have up to 4 axles and can also be used with electric over hydraulic systems, it is very versatile. As your vehicle is already set up to be used with a brake controller, it makes the installation significantly easier as well. You will need to pair the P2 controller with the Tekonsha Plug-In wiring adapter # 3021-P as this will plug...

There are lots of these units out there as many owner's end up replacing the OEM units with better-performing aftermarket controllers like the Prodigy P3 # 90195. The controller does not require any programming to operate. The vehicle computer may need to be flashed by the dealer if you find you get error messages...

All you will need is wiring harness # 3021-P to be able to plug right into that connector under the dash that you mentioned.

Since the display is flashing between .C. and N.C. this means the controller boost setting is set and the controller is not detecting the trailer connection. The boost feature being set is not a problem, but you should make sure the trailer connectors are mated properly. First, check to be sure all of your trailer brake magnets are properly grounded. Next, make sure the trailer connectors do not have...

- Brake Controller Wiring Harness for a 2015 Ram 1500For a Tekonsha brake controller such as the P2, # 90885, you would use wiring harness # 3024-P for your 2015 Ram 1500. If you have a different manufacturer brake controller let me know what it is and I can determine the correct harness.
view full answer... - Which Brake Controller Adapter for 2019 Ram 1500 with Tekonsha or Curt Brake ControllerThe plug and play brake controller adapter will vary depending on what brake controller you're using, but if you've got a Tekonsha brake controller like the Prodigy P3 # 90195 then you'll want to use the # 3024-P on your 2019 Ram instead of the # 3021-P that you used on the 2010 Ram. If you're using a Curt brake controller like the Assure # C49UR then you'll want to use the # C51458. If you've got a different brake controller than a Curt or Tekonsha just let me know what brand you're using...

When you step on the brake, the red wire should show a signal. If it does not, that means the controller is not receiving a signal from the brake pedal. If you hardwired the controller, check the red wire connection to be sure it is attached to the correct wire on the brake switch above the brake pedal. You need the wire...
view full answer... - Brake Controller and Install Recommendation for a 2011 Dodge RamThe connector under the dash that would be used for a brake controller should be a blue connector like what is pointed out in the picture I attached. It sounds like you have found a different connector that is not for a brake controller. The # 3021-P harness would be the correct harness to connect a Tekonsha brake controller like the P2 part # 90885 that is our best seller because of how well it works and how easy it is to install. I also attached an install video for you to check out as well.

- Does Installing Tekonsha Powertrac on 2012 Ram 1500 Using Tekonsha Harness Require Dealer Visit The Tekonsha Powertrac part # 39523 with the install harness part # 3021-P will easily install in your 2012 Ram 1500 and won't require you to take the truck to a dealer to reprogram it. You'll basically just plug in the controller under your dash using the adapter and you'd be set.

This is most likely an issue on the black power wire for the controller and how it attaches to the truck. Make sure it is making a solid connection the vehicle battery through a circuit breaker that is functioning properly.

- Replacing Factory Brake Controller On Dodge Ram Truck I called my contact at Tekonsha and asked about replacing the Dodge Integrated Brake Controller if the truck is a 2010 through 2015. If you have a different year Ram just let me know and I can make some recommendations that will work for you. They told me the best way to go about replacing the controller is to take the vehicle to a Dodge dealership and have them disconnect the ITBM.

view full answer... - Troubleshooting Electric Trailer Brakes on 2012 Dodge Ram 4500 with Factory Brake ControllerIt sounds like it is a brake controller issue and those factory integrated controllers are not very reliable. I recommend the Tekonsha Prodigy P3 # 90195 to replace your factory controller. It can be installed using the wiring adapter # 3021-P which plugs into a harness under your dash. It will be to the left of the steering column, taped to another harness near the emergency brake pedal.

If it is a 1995 to 2009 1500 you will need harness # 3020-P If it is a 2010 to 2012 1500 you will need harness # 3021-P If it is a 2013 to 2014 1500 you will need harness # 3023-P And if it is a 2015 1500 you will need harness # 3024-P

For the 2010 model year, Dodge did indeed change the brake controller connector under the dash. The # 3020-P wiring harness that your old truck used won't work on your new one. For the 2010, you'll need the # 3021-P wiring harness. The connector that the harness will plug into is located under the dash between the steering column and the emergency brake pedal, as shown in the photo I've provided for you.
